HI,
1. I want to interchange two diffrerent heaters on the same heater controller. One is 1.5 Amp the other is 10 Amp. Article 210.20 calculated the OPCP at 10 X 1.25 = 12.5 amp next up is 15Amps. 210.20 says not less than. So would this be OK for the smaller heater over current protection ? The wiring and everything else would be sized for the larger heater.
2. This heater is used on a vessel (tank) to heat a product. I think this is covered by article 427. This says the heater must be protected by ground fault protection called GFEPCIs. I've never heard of this. Where can I find them?
Thanks.
